[Paraview] Down sample data?

[Andy Bauer]

You could try the Append Attributes filter instead of the programmable
filter if the geometry is the same for both/all inputs into the Append
Attributes filter. To use the Append Attributes filter just select the
filters in the Pipeline Browser that you want to compare.

Note that for 5.4.1 and earlier you'll need to use something like the
Calculator filter to rename the arrays while for the 5.5 release candidate
it will do automatic renaming for you.
